Two horizontal lines are drawn on a canvas, each connecting a fixed left point to a moving right point. The right point animates back and forth between two positions, causing the line to redraw smoothly with a zigzag or "funky" pattern along its length. The example uses a custom D3 curve, `d3.funkyline()`, applied via `d3.line()` with a Canvas 2D context, and animates using `transition.attrTween` and a recursive `transition` loop. The line’s wavy offset is controlled by interval and margin parameters, while a small circle marker updates its position in sync with the animated endpoint.

Testing Lines on D3

This example animates a dynamic array of white circles and connecting lines, whose positions, radii, and line endpoints oscillate smoothly over time against a black background. Using D3.js v7 with the `select`, `range`, and data-join methods, it updates the SVG scene at 60 frames per second via `setInterval`, employing `.join()` to manage entering and exiting elements. The animation’s motion is driven by trigonometric functions, including sine and tangent, applied to the current time variable `t`.

D3 Path Examples

This example demonstrates how D3.js can draw and animate SVG paths from simple coordinate datasets, including diagonal and horizontal lines, multipoint curves, triangles, and rectangles. The code defines multiple data arrays and uses the `d3.svg.line()` API with various interpolation types to render static shapes, while separate functions animate paths by transitioning the `d` attribute using `transition().duration(6000)`. One animation elongates a horizontal line by mutating the dataset’s endpoint, and another shifts the line’s origin point, both relying on D3’s built-in transition system. The page sets its frame height to 1800 pixels to accommodate the multiple SVG canvases.

D3 Line - Rendering Line in a canvas context

This example demonstrates how to render a line chart directly onto a canvas element using D3’s `d3.line` generator with a custom rendering context. A simple dataset of five coordinate pairs is drawn as a single path, with the line generator’s `context` method set to the canvas’s 2D drawing context. The code explicitly manages the canvas stroke styling and path initialization, bypassing SVG entirely. It relies on D3 v7 and the native Canvas API’s `getContext('2d')` and `stroke()` methods to produce the final output.

Canvas Animation Using D3.js

This example demonstrates how to apply D3.js’s enter-update-exit pattern and transitions to custom DOM elements, then render their positions and radii onto an HTML5 canvas. A dat.GUI control regenerates randomized circle data, triggering smooth positional and size animations on custom `<c>` nodes. A `MutationObserver` watches attribute changes on a custom element container and redraws the canvas whenever those animated attributes update, bridging the gap between D3’s DOM-centric data joins and canvas-based rendering. The code uses `d3.select`, `transition.attr`, and the Canvas 2D `arc` API.

Zoom Transitions

Animated grid lines on a canvas demonstrate D3’s zoom transitions, which smoothly pan and scale the view every five seconds to a new random location. The example uses `d3.behavior.zoom` with linear scales, and `transition.call` to invoke the zoom’s translate and event methods. Grid rendering relies on the Canvas 2D API, drawing vertical and horizontal lines based on the current domain, with line width scaling by zoom level.

D3 Selections

This example demonstrates a dynamic line chart created with D3, where 15 points oscillate vertically over time based on a sine function. The visualization uses D3's `select` and `range` APIs to build an SVG canvas and animate both circles and a connected path. Using D3's `.join()` method, the code efficiently updates element attributes on each frame, with a `setInterval` timer driving the animation at 20ms intervals. The implementation uses the React framework and renders purely through SVG elements, with the data generated procedurally from a mathematical function rather than external sources.

Canvas, Lots of Transitions

A grid of 19,200 small rectangles fills the canvas, each transitioning from steelblue to lightgreen while moving from the top-left corner to the bottom-right. The animation uses d3.v4 transitions with staggered delays based on each cell’s grid position. Rendering is handled by Canvas 2D API calls within a `requestAnimationFrame` loop, while a detached custom D3 selection manages the rectangle attributes without creating DOM elements.

D3 Selection Exploration - Assignmnet with line

The visualization animates a line connecting a set of circles that move and pulse in a sinusoidal pattern. Each circle’s position and radius oscillate over time, and a black polyline path links them in sequence. Built with D3.js v6, the code uses the `select` API to append an SVG canvas and the `line` and `range` generators to compute the path and data. The `setInterval` loop updates the `t` time variable, invoking `vizData` to redraw the circles and path at 60 frames per second with declarative join operations.
